Struct TextRankSummarizer 

pub struct TextRankSummarizer {
    pub damping: f64,
    pub n_iterations: usize,
    pub similarity: SentenceSimilarity,
}

Extractive summariser based on the TextRank algorithm.

Sentences are represented as graph nodes; edges are weighted by sentence similarity. PageRank is run to score each sentence.

Fields

damping: f64

PageRank damping factor.

n_iterations: usize

Number of PageRank iterations.

similarity: SentenceSimilarity

Similarity metric used to weight graph edges.

Implementations

impl TextRankSummarizer

pub fn new( damping: f64, n_iterations: usize, similarity: SentenceSimilarity, ) -> Self

Create a summariser with custom parameters.

pub fn summarize(&self, text: &str, n_sentences: usize) -> Result<String>

Summarise text by extracting the top n_sentences ranked sentences.

Sentences are returned in their original document order.

Trait Implementations

impl Clone for TextRankSummarizer

fn clone(&self) -> TextRankSummarizer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TextRankSummarizer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TextRankSummarizer

fn default() -> Self

Returns the “default value” for a type.
